    pair of scissors, in order to enable the acid to come in contact with the living surface. Largely diluted (as 50 or 60 drops of strong acid to a pint or qnart of water), it is recommended by Sir Astley Cooper as a wash for sloughing and other ill-conditioned sores. Pharmaceutic Uses.—Nitric acid is used as an oxidising agent in the production of diluted phosphoric acid, solution of perchloride of iron, solution of persulphate of iron, and several other preparations. It is also used in the following preparations :— [§ Acidum Nitricum Dilutum. Diluted Nitric Acid. Take of Nitric Acid . . . . .6 fluid ounces. Distilled Water . . . .a sufficiency. Dilute the acid with 24 fluid ounces of the water, then add more water, so that at a temperature of 60° it shall measure 31 fluid ounces. Or as follows :— Take of Nitric Acid ..... 2,400 grains. Distilled Water . . . .a sufficiency. Weigh the acid in a glass flask, the capacity of which, to a mark on the neck, is one pint; then add distilled water until the mixture at 60° temperature, after it has been shaken, measures a pint. Characters and Tests.—Colourless. Specific gravity, 1*101. 361*3 grains by weight (6 fluid drachms) require for neutralisation 1,000 grain-measures of the volumetric solution of soda, corresponding to 14*95 per cent, of anhydrous nitric acid. Six fluid drachms, therefore, correspond to 54 grains of the anhydrous acid (one equivalent of N05, or half an equivalent of N205). Dose, 10 to 30 minims.] [§ Acidum Nitro-Hydrochloricum Dilutum. Diluted Nitro- Take of Hydrochloric Acid. Nitric Acid . . . . .3 fluid ounces. Hydrochloric Acid . . . .4 fluid ounces. Distilled Water . . . .25 fluid ounces. Mix the acids, and allow them to remain for twenty-four hours in a bottle, the mouth of which is partially closed ; then add the water in successive portions, shaking the bottle after each addition, and preserve the mixture in a stoppered bottle. Characters and Tests.—Colourless. Specific gravity, 1*074. 352*4 grains by weight (6 fluid drachms) require for neutralisation 920 grain-measures of the volumetric solution of soda. Dose, 5 to 20 minims.]
